So first you multiply 2 and 4x to get 8x. Then you multiply 2 and 5 to get 10. So the problem will look like:
8x+10=90
Then you subtract 10 on both sides of the problem to get:
8x=80
And then divide 8 on both sides to get
x=10
Answer:
She got 5 incorrect.
Step-by-step explanation:
In order to find this, we start by using the formula for percentage.
Correct/Total = Percentage
Now we put in known quantities.
Correct/25 = .8
Now to solve we multiply both sides by 25
Correct = 20
Since she got 20 correct, we know she got 5 incorrect
2 ham/wheat 5 ham/white 9 ham/rye 4 turkey/white 5 turkey/wheat 5 turkey/rye
I think this is right
Answer:
(6r+7)+(13+7r)=13r+20
(13-1/2r)-(1-r)=12-1/2r
(-8-r)+(2r-4)=-12+r
Last one is r-13/6
